IMPROVEMENT IN crows.

Spec-ific-aiion forming part of Leiters Patent No. 141,960, dated August19, 18 23; application filed July 11, 1873.

I of the city of Richmond, in the county of Hen- .rico and State ofVirginia, have invented certain new and useful Improvements in Flows;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it,

reference being had to the accompanying drawings, which form part ofthis specification, in whichi Figure 1 is a side View of the plow; Fig.2, a view of the standard with the front piece, mold-board, andsharedetached; Fig. 3, a view of the point Fig. 4., a view of the frontpiece; Fig. 5, a view of the mold-board; Fig. 6, a view of the share.

This invention relates to mold-board plows, used for turning the soil.The object is to make all the parts in separate pieces, each piece beingproduced with flanges or lugs, and the adjoining pieces withcounterparts, so that when brought together each supports andstrengthens the other, so that very few bolts are required to firmlybindthe whole together.

When Worn out or broken, any piece or partmay be readily replaced with anew one, thus saving much time and expense in making repairs.

The nature of my invention consists in so constructing the standard,front piece, moldboard, and point that each piece can be molded and castin a simple, plain piece of casting,

made in what is known by molders as a twopart fiask--the simplest kindofcasting and it consists, further, in forming each part of the' plow asshall be hereinafter more fully set forth. My object to is make a plowthat will be simple and cheap in its construction,

and that will admit any one part, when worn out, to be readily replacedat a trifling eX-' pense.

In Fig. 1, R is the standard; 0, the moldboard; I, the share; H, thepoint and r the rear end of the land-side plate. 8 is a groove,

groove 8, and is provided on its lower end with a flange, 10, upon whichthe rear end of the beam rests. 3 is a flange that prevents the forwardend of the beam from tilting, and j is a hole to receive a bolt thatattaches the forward end of the beam to the standard. Bolts pass throughthe holes jj to fasten the handles of the plow to the standard.

In Fig. 2, It is the standard cast with the flange I) and lugs 01 e,which are to aid in supporting the front piece of the plow, and with theswell f, side A, whose upper outer edge is beveled to receivethe'beveled flange E of the mold-board, bottom B, and projection 9, allof which form part of a mortise for the reception of the tenon a of thereversible wedge-shaped plow-point H; and with the holes h a, through Iwhich bolts pass for attaching the land side plate and the front pieceto the standard. a is the rear end of landside plate.

In Fig. 4, K is the front piece of the plow, with flange d formed sothat it will pass between the lug d and flangev b of the standard. 0 isa fork on and at an oblique angle to the front piece K, and is toreceive a belt that passes through hole a of the standard. 0 is a recessto receive the lug cot the standard;

and D d are sides of the front piece, with a' flattened surface, d, atthe top for supporting the flange c of the mold-board, and aid informing the mortise to receive tenon a of the point H; and m is toreceive a bolt that fastens the share to the front piece.

In Fig. 5, O is the moldrboard, which is bolted to the front piece K bya bolt passing through hole 41 of mold-board and hole h in the frontpiece,and it has abeveled flange, E, that bears upon the beveled side Aof the standard, and a flange, c, that rests on the flattened surface 0'of front piece K. Now, when the standard, front piece, and moldboard arebolted together, a mortise is formed for the reception of the tenon ofthe point.

In Fig. 3, H is the beveled wedgeshaped plow-point, with tenon a to fitinto the mortise formed by the standard, front piece, and molda pressingagainst the walls of the mortise,

and by aid of the projections F on the share I. The point H isreversible, and has its upper and lower surfaces made with the samepitch.

In Fig. 6, I is the share, which is made reversible, and is bolted tothe front piece K by a bolt passing through the holes I m. F F areprojections on both ends of the share, and are to assist in holding thepoint H in the mortise, as well as to support the share, by entering thegroove G in the point.

I have described all the parts as formed by casting, but some of themmay be formed by stamping wrought iron or steel plates in dies. They maybe cast in steel or any of the composition metals suitable for thepurpose.

Having described the construction of the parts of the plow, I will nowmention how they may be put together. It is as follows: The projection don the front piece is placed between the flange b and lug d of thestandard, when it will be found that lug 0 has entered the recess 0 onthe front piece and that the fork c is directly over the hole a in thestandard. A bolt is now put through hole a in the standard and throughthe fork c of the front piece, after which a nut is screwed down tightlyon the bolt, securing the front piece firmly to the standard. Theland-side plate is next placed in position and a bolt put through it andthe hole h of the standard, and a nut applied. The mold-board is nowplaced on the standard, with its beveled flange E and flange a restingupon the beveled side A and flattened surface d of the standard andfront piece, respectively, and a bolt passed through the hole 2' in themold-board and then through hole h in the front piece, after which a nutis screwed onto the bolt, whose point is now on the under side of thefront piece. The mortise is now complete, and tenon a of the point H isinserted into it.

The next step is to place the share I in position on the front piece,one of the projections F entering the groove G of the point H, and topush a bolt through the hole l of the share and m of the front piece,and screw a nut onto it.

The upper side of the beam bears against the flange 1 of the standard,and a bolt is passed through it and the hole j of the standard. Theunder side of the rear end of the beam is now placed on the flange w ofthe plate a, and the bolt that passes through the slot in the grooves,and the plate 2; is continued through the beam,'and, after the beam hasbeen suitably adjusted by means of the plate '0, a nut is applied to andscrewed down tightly onto the bolt, holding the beam firmly in place.

The handles are attached to the plow by bolts passing through them andthe holes j j of the standard.

The parts of my plow can be made cheaply by casting or molding themseparately in a single two-part flask; or they may be formed by stampingthem from wrought-iron or steel plates, in dies. It will also be noticedthat if any one part of a plow be worn out or broken before another partit can be replaced in a short time and at a little cost.

There are other advantages obtained by my invention that are toonumerous to mention in this specification.

I am aware that there are bits and nibs -for plow-points made separatefrom the share, and which fasten without bolts. I am also aware thatthere are reversible points, but they require fastenings of variouskinds.

The plow may be readily taken to pieces and put together by any one, sothat all the parts may be packed in a small space for transportation orstorage.

It will be noticed that I have referred to a process of casting; but Ido not claim it, as it is old, and have merely mentioned it to show theadvantages of my invention.

Having thus described my invention, I claim- 1. The standard It, withbeveled side A, bottom B, projection g, and swell f, as and for thepurpose described.

2. The front piece K, with flanged, fork c, recess 6, sides D d, andflattened surface d, as and for the purpose set forth.

3. The front piece K, flange d, fork 0, recess 0, sides D d, andflattened surface 61', in combination with flange I) and lugs 01 e onstandard R, as and for the purpose set forth.

4. The mold-board (3, with beveled flange E and flange 0, as and for thepurpose set forth.

5. The mortise formed by combining the standard, front piece, andmold-board, substantially as shown and described.

6. In a plow, the combination of standard, front piece, and mold'board,each having the form substantially as shown and described.

7. The single wedge-shape plow-point H,

, provided with a ten on, a, and having a groove,

G, on each of its two sides, running parallel to the length of the tenonand terminating so as to leave a space between it and the shoulder, inorder to fasten the point by means of the share, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this10th day of July, 1873.
